The folks at Adafruit are busy as a bee working on bringing some of their really cool boards to the Raspberry Pi platform. Here’s a few that came in over the last few days:
16 servos is almost too manyServos require a PWM output but the Raspi only has hardware support for PWM on a single GPIO pin; certainly not enough to build a gigantic, city-leveling robot. [Kevin] over at Adafruit put together a tutoria (http://learn.adafruit.com/adafruit-16-channel-servo-driver-with-raspberry-pi/overview)l for using this 16 channel servo driver (http://adafruit.com/products/815) with the Raspi.
12 bit DACWith only one PWM pin and no analog out, it was only a matter of time before someone hooked up the Adafruit 12 bit DAC to the Raspberry Pi (http://learn.adafruit.com/mcp4725-12-bit-dac-with-raspberry-pi/overview).
16×2 LCD displaysBoth the servo and DAC builds use the Adafruit I2C library (https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code) and a bit of Python. Of course it’s possible to treat the GPIO pins on the Raspberry Pi as digital outs, just as [Mikey] did with his Raspi LCD display tutorial (http://learn.adafruit.com/drive-a-16x2-lcd-directly-with-a-raspberry-pi).
So, what distro are you using?Of course all these builds use Adafruit’s Occidentalis distro (http://learn.adafruit.com/adafruit-raspberry-pi-educational-linux-distro/occidentalis-v0-dot-1), a maker-friendly Linux distro we’ve posted about before. It’s too useful to languish as a single Hackaday post, so here it is again.
